The integration of the revised attrition calculation left the Concepts Evaluation Model (CEM) with the following discrepancies: (1) Two separate attrition algorithms were required for the same engagement. The two calculations were independent and could result in overstating the combat losses. (2) Artillery firepower was equally distributed among all targets and an expected quantity of ammunition was expended regardless of availability of targets. The objective of this study is to continue modifications to the CEM to eliminate dependence of artillery and tactical air weaons upon firepower potential and integrate these weapons into the new attrition algorithm: (a) In accordance with the design specifications develop new and modify existing CEM subroutines as required to incorporate artillery and air into the new attrition process. (b) develop a set of representative data inputs and conduct limited testing of the integrated process.
